Type material.— ARGENTINA. HOLOTYPE: male ( INHS), “ Salta / Dto. La Capital / Salta. 13 Jan. 1988 / Heath-Sanborn-/ Noriega Coll.” . PARATYPES: five male and two female same data as holotype (three male and one female MSHC, two male and one female AFSC) ; two male (one male MSHC, one male AFSC) “ Salta / Ciudad Salta / 12 Jan. 1988 / Heath-Sanborn-/ Noriega Coll.” ; one male ( MSHC) “ Salta / Dto. La Caldera / Ruta 9 & Rd 11 to Grl / Guemes. 13–I–1988 / Al Sanborn Coll.” ; one female ( MSHC) “ Salta / Ruta 68 & Rio Pulares / 1 km No. of El Carril / 16 Jan. 1988. Heath-/ Sanborn-Noriega Coll.” ; one male ( MSHC) “ Salta / Yatasto / 17 Jan. 1988 / Heath- Sanborn-/ Noriega Coll.” ; two male ( MSHC) “ Salta / Ruta 9–16 km No. of / Prov. Tucuman / 17 Jan. 1988. Heath- / Sanborn-Noriega Coll.” .

Etymology. The species is named for the deep shade environment within the tropical forest that the species inhabits.

Diagnosis. — Herrera umbraphila sp. n. can be differentiated from H. humilastrata sp. n. and H. lugubrina compostelensis by the dorsal thoracic markings present in these species. Both H. coyamensis and H. infuscata are castaneous colored species and H. lugubrina lugubrina and H. laticapitata are primarily black species instead of the green and tawny coloration found in H. umbraphila sp. n. The most similar species to H. umbraphila sp. n. in coloration pattern is H. ancilla , but H. ancilla is smaller (about 11.5 mm vs. 13 mm), the abdomen is darker, there are fewer timbal ribs (five vs. 11 ribs), and the male operculum is a finger-like projection rather than a plate-like extension.

Description

Coloration.—Ground color of head and thorax green; abdomen tawny.

Head.—Slightly wider than mesonotum (about 1.06X) with transverse piceous mark through lateral ocelli between eyes, extending anteriorly to encompass median ocellus, not reaching frontoclypeal suture, epicranial sutures and spot on posterior head between posterior cranial depression and eye green, anterior extension of mark varies from reaching the posterior half of the median ocellus to reaching the frontoclypeal suture in paratypes. Ocelli rosaceous, eyes dark green. Silvery pile posterior to eye and on ventral head. Postclypeus green, rounded anteriorly, centrally sulcate with 10 transverse grooves and silvery pile laterally. Anteclypeus green with silvery pile. Rostrum green with piceous tip, reaching to posterior coxae. Gena green. Lorum green with tawny spot near junction of postclypeus and anteclypeus. Scape green, proximal pedicel tawny, remaining antennal segments fuscous.

Thorax.—Green to tawny with almost no marks or with very few markings. Pronotum with fuscous marks in ambient fissure on midline and on lateral margin of lateral portion of pronotal collar. Mesonotum green, scutal depressions light tawny, silvery pile laterally. Submedian and lateral sigillae faded to light tawny in some paratypes. Wing groove tawny. Metanotum tawny posteriorly, piceous anteriorly. Ventral thoracic plates greenish ochraceous becoming ochracous on posterior thorax except tawny spot on posterior katepisternum 2 and posterior episternum 3, episternum 3 spot absent in some paratypes. Venter covered with dense, long, silvery pile.

Forewing and hind wings.—Hyaline. Venation green becoming testaceous distally except piceous basal half of posterior margin of testaceous anal vein 2 + 3 and small piceos spot at base. Basal cell hyaline. Basal membrane gray and green. Hind wing venation ochraceous becoming fuscous distally except green cubitus anterior. Vanal fold, anal cell 3, anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2, base of cubital cell 2 and base of medial cell grayish tawny. Green faded to ochraceous in some paratypes.

Legs.—Ochraceous green and tawny. Piceous mark on lateral middle and hind coxae. Fore femur with oblique primary spine, less oblique secondary spine, tertiary spine parallel to primary spine and small, oblique distal spine. Spines fuscous and piceous with green base, decreasing in size distally. Fore tibiae, distal middle tibiae, and distal end of hind tibiae tawny, amount of tawny decreased in some paratypes, tibial spurs and combs castaneous with piceous tips. Tarsi tawny. Pretarsal claw tawny with fuscous tips.

Operculum.—Male operculum ochraceous, not reaching posterior margin of sternite II. Lateral margin straight, posterior margin curved, medial margin rounded, medial margins not touching, anteromedial margin angled to base. Meracanthus ochraceous with fuscous spot on medial anterior base, reaching to anteromedial margin of operculum. Operculum covered with silvery pile that also radiates from margin. Female operculum with angled lateral margin, straight posterior margin, medial margin rounded near base, reaching to anterior of sternite II posteriorly and lateral meracanthus medially. Meracantus ochraceous, longer than operculum.

Abdomen.—Dorsal tergites greenish laterally marked with tawny, fuscous and piceous. Tergite 1 piceous with fuscous anterior and posterior medial margins. Tergite 2 piceous along posterior opening to timbal cavity, anterolaterally and on auditory capsule, fuscous medially with ferruginous hind margin. Timbal with 11 ribs. Tergite 3 tawny medially, fuscous anteromedially, with tawny lateral spot. Tergites 4–8 tawny centrally with fuscous posterior margin expanding on either side of midline and fuscous lateral spots, proportion of green decreases and proportion of tawny and fuscous increase posteriorly in tergites 4–7, dorsolateral tergite 8 with large green spot. Tergites covered with silvery pile, more dense laterally. Sternite I ochraceous with posteromedial fuscous spot, sternite II piceous with ochraceous anteromedial expansion and green spot on medial angle of opening to tympanal cavity, sternites III and IV piceous medially, green laterally, sternite V–VII piceous, sternite VIII tawny with piceous base. Epipleurites 3–6 green, 6 and 7 piceous. Female sternites tawny with medial piceous stripe. Silvery pile on sternites, long golden pile on posterior sternite VIII.

Male genitalia.—Pygofer greenish laterally, tawny dorsally with fuscous dorsal beak, anal styles ochraceous not reaching to end of dorsal beak. Pygofer upper lobe folded medially, pygofer basal lobe small, rounded, bent medially. Long golden pile radiating medially inside pygofer. Uncus lobes very small. Claspers with broad base, thinning and bending at a right angle before expanding and splitting into a pincer-like structure, the posterior branch bifurcates again near the terminus. Aedeagus tubular with flattened ventral terminus, castaneous.

Female genitalia.—Sternite VII piceous medially, tawny laterally with long silvery pile laterally, posterior margin with deep medial notch, lateral posterior margins angulate. Abdominal segment 9 tawny dorsally, large dorsolateral fuscous stripes not reaching posterior margin, ochraceous laterally, covered with silvery pile. Ochraceous region may have faded from green. Anal styles tawny, not as long as dorsal beak. Gonocoxite IX tawny, ovipositor sheath piceous with long white pile near tip. Gonapophysis VII and X dark tawny. Ovipositor sheath extending beyond tip of dorsal beak.

Measurements (mm).— N = 12 males or 3 females, mean (range). Length of body: male 13.5 (12.5–14.4), female 14.9 (13.4–15.8); length of forewing: male 18.0 (16.3–18.6), female 20.1 (18.4–21.0); width of forewing: male 6.7 (6.2–7.0), female 7.3 (7.0–7.6); length of head: male 2.5 (2.2–2.7), female 2.6 (2.4–2.7); width of head including eyes: male 4.8 (4.6–5.0), female 5.1 (4.9–5.2); width of pronotum including suprahumeral plates: male 5.4 (5.0–5.6), female 5.7 (5.1–6.1); width of mesonotum: male 4.7 (4.4–5.0), female 5.0 (4.8–5.2).

Notes. — Herrera umbraphila sp. n. is from the understory vegetation in the Yunga floristic province. The species has been shown to have unique thermal adaptations to the understory environment ( Sanborn et al. 2011a).
